VAPORIZER.

Speclcation of Letters Patent.

Patented July 16, 1918.

Application filed March 21, 1917. Serial No. 156,506.

To all whom t may concern:

Be it known that I, JAMES I. GARDINER, citizen of the United States, residing at Seattle, in the county of King and State of lVashington, have invented a certain new and useful Improvement in Vaporizers, of which the following is a specification.

My invention relates to improvements in vaporizers, and the object of my invention is to provide a vaporizer which shall embody a container within which may be disposed a body ofvolatile combustible fluid, as gasolene, kerosene and the like, and which shall be adapted to vaporizc such fluid quickly, and thoroughly mix the resultant vapor with air to form a combustible gaseous mixture for internal combustion engines, gas stoves and gas burners.

I accomplish this object by devices illustrated in the accompanying drawings, wherein- Figure l is a view in vertical mid-section 0f a vaporizer embodying my invention.

lFig. 2 is a view of the same in horizontal section on broken line 2, 2 of Fig. 1 and with the balls 49 omitted.

Fig. 3 is a view of the same in horizontal section on broken line 3, 3 of'Fig. l.

In Figs. l, 2 and 3 I have shown a preferred form of vaporizer wherein is ernbodied a container of cylindrical form hav ing a bottom wall 33, from which extends vertically upward an outer cylindrical wall 34 and an inner concentrically disposed cylindrical wall 35, whereby is formed an annular space 36 between the cylindrical wall 35 and the cylindrical wall 34.

Adjacent to the bottom wall 33 the inner cylindrical wall 35 is provided with a plurality of holes extending therethrough, as holes 37, whereby fluid may flow between the space within the cylindrical wall 35 and the Space 36.

The inner cylindrical wall 35 extends upwardly to project for a distance beyond the top edge of the outer cylindrical wall 34 and the upper end portion of said inner wall 35 is provided with an external screw-thread, upon which screw-thread is screwed the larger and bottom end portion of a nipple 38, of the form of the frustum of a cone, whose smallerA and top portion connects with the lower end of a conduit pipe 39 that may be extended to a desired point of delivery.

Integral with the upper end portion of the inner wall 35, at a point adjacent to the lower end of the nipple 38, is an annular flange 40 that extends in a horizontal plane spaced from the top edge of the outer cylindrical wall 34 to a circular' line that is larger in diameter than the diameter of said outer cylindrical wall 34 and the outer edge portion 41 of said flange 40 is turned downwardly and provided with an internal screwthread, into which screw-thread is fixed the screnhthreaded upper end portion of the cylindrical wall of an inclosing case 42 whose internal diameter is greater than the external diameter of the outer cylindrical wall 34, whereby is formed an annular space 43 between said cylindrical wall 34 and the cylindrical wall of said inelosing case 42.

The lower end portion 44 of the inclosing case 42 extends downwardly lower than the plane of the bottom wall 33 of the container and such lower end portion 44 is constricted in its diameter and is provided with an internal screw-thread into which is fixed the upper screw-threaded end of a nipple 45, of semispherical form, into the bottom end of which is fixed the upper, end of a conduit pipe 46 which may be extended to connect its other end with a source of supply of air under pressure, not shown.

rIhus air under pressure may be caused to flow through the annular space 43 over the top edge of the outer cylindrical wall 44, thence downwardly through the annular space 36, thence through the holes 37, thence upwardly through the space within the inner cylindrical wall 35, thence through the nipple 38 into and through the conduit pipe 39 to a desired point of delivery.

Within the upper end portion of the inner cylindrical wall 35 is fixed two wire woven screens 47 and 48, respectively, and within the space between the screens 47 and 48 are disposed a plurality of balls or marbles 49.

Fixed in the bottom wall 33 within the cylindrical wall 45 are the bottom ends. of three metal rods 50, which are disposed equidistant from each other, in a circle concentric with the cylindrical wall-45 and said rods 50 extend upwardly to a plane spaced from the plane of the screen 48.

Upon each of the rods 50 are three separate helical springs, as springs 51, 52 and 53, and slidably mounted on said three rods 50, to be guided thereby, are three circular screens, 54, and 56, the screen 56 being resiliently disposed between the upper ends of the springs 53 and the lower ends of the springs 52; and the screen 55 being disposed between the upper ends of the spring 52 and the lower ends of the springs 51, while the screen 54 is disposed to rest on the upper ends of the springs 51 where it is lim1ted with respect to upward movements by nuts 57.

Thus, the screen 54, under normal conditions of operation, will be stationary in its position shown in Fig. 4, while the screens 55 and 56 will be adapted to vibrate in vertical directions in response to a varying force of air flowing upwardly through them.

Extending through the central portion of the bottom wall 33 is an inlet passageway to which is connected-a short conduit pipe 58 that extends vertically downward and to the lower end of which is connected a nipple 59 which extends horizontally through the .lower end portion of the inclosing ease 42, and to the outer end of said nipple 59 is connected a pipe 60 by means of a union 61.

The pipe 60 may serve as a supply pipe Awhich may be extended to a source of supply (not shown) of combustible liquid, as gasolene, kerosene or other volatile combustible liquid, and said pipe 60 is provided to admit said combustible liquid into the container' in such quantity as will raise its surface in the annular space 36 and in the space within the cylindrical wall 35 to the height indicated by the broken lines 62, shown in Fig. 4, whereby the screen 54 will be slightly above the surface'of said liquid.

The mode of operation of the structure illustrated in Figs-1, 2, and 3 is asI follows: The air under pressure of an air pump may be forced through the pipe 46 into and through the vaporizer as may be desired under some conditions of use, and under other conditions of use air may be drawn through the vaporizer by suction.

In its operation the structure of Figs. 1, 2 and 3, air flowing under pressure of an air pump or drawn by suction through the pipe 46 flows upward through the annular space 43, thence downwardly through the liquid contained in the annular space 36, thence through the holes 37, thence upwardly through the liquid and screens 56 and into the space above the surface of the liquid and through the screen 54, thence through the screen 48, at which point such air will be charged and thoroughly mixed with vapor of the combustible liquid to form a combustible mixture of gases which may then flow upwardly from the screen 48 through the interstices of the marbles 49 and through the screen 47 into and through the pipe 39 to the point of combustion or t0 the point of delivery of such mixture of gases.

It is manifest, that the resiliently mounted screens 55 and 56 will serve to agitate the surrounding liquid and air to cause such air to be subjected to intimate contact With the liquid2 thereby to cause a more rapid volatilization or vaporization of said liquid.

Obviously, changes may be made in the forms, dimensions and arrangement of parts of my invention Without departing from the spirit thereof.

What I claim is:

A vaporizer of the class described including a container having a bottom wall, spaced inner and outer Walls formed integrally with the bottom wall, the upper edge of the inner wall extending upwardly beyond the edge of the outer wall, a cover formed on the extended portion of said inner wall and projecting laterally beyond the outer wall, a casing removably secured to the cover and inclosing said container and having its walls in spaced relation to the upper wall, an air pipe connected to and communicating with the bottom' Wall of the casing, an outlet pipe connected to the upper edge of the vinner wall and communicating with the container, a plurality of vertical spaced rods secured to the bottom wall and located within the inner wall, spaced baille screens mounted upon said rod and means for supplying fuel to the container and within the inner wall.

In witness whereof, I hereunto subscribe my name this 8th day of March, A. D. 1917.

. JAMES I. GARDINER.
